These crumbly apple streusel muffins are sure to become your new favorite treat. They are perfectly spiced with cinnamon and nutmeg, and bursting with fall flavor in each bite!
Prepare the streusel by mixing the flour, sugar, brown sugar, and cinnamon together. Cut in the butter using a pastry cutter or a fork until you have pea-sized lumps remaining
In a large bowl whisk together the eggs, sour cream, melted butter, and sugar.
In another bowl whisk together the flour, baking powder, baking soda, salt, cinnamon, and nutmeg.
Add the dry ingredients to the wet ingredients and mix until just combined. Stir in the apples. Use a large cookie scoop to fill the baking cups 2/3 of the way full. Sprinkle the streusel over the tops of the muffins.
Bake for 20-25 minutes, until starting to turn golden brown and set in the center. Allow the muffins to cool before serving.
